DETAILED DESCRIPTION

Various exemplary embodiments relate to a fluid filtration system, for example a fuel filter system, that incorporates a filter cartridge and a filter cartridge housing a flow restriction valve for the purpose of preventing fluid flow through the system in the absence of a filter cartridge or where an incorrect filter cartridge is installed in the filter cartridge housing. The fluid filter system may be employed in any appropriate vehicle or engine application. According to one embodiment, the fluid filter system may be employed in a diesel engine application.

According to an exemplary embodiment, the fluid filtration system is a “no filter, no run” system. A “no filter, no run” filter system is a system designed such that fluid flow through the system is prevented altogether or permitted in an amount insufficient to allow engine operation when no filter cartridge or an incorrect filter cartridge is installed in the system. In one embodiment, the filter system may be configured to allow some fluid to pass through the flow restriction valve even when no filter cartridge or an incorrect filter cartridge is installed. The filter system may be configured to allow sufficient fluid to pass through the flow restriction valve to lubricate elements downstream from the filter system and prevent damage thereto but not allow engine operation.

According to an exemplary embodiment, the filter cartridge includes geometrical features that correspond to features of a filter cartridge housing. For example, the filter cartridge may include a geometric projection that corresponds to an opening of a flow restriction valve provided in the filter cartridge housing, preventing fluid flow out of the filter housing in the absence of a filter cartridge with the appropriate geometric projection. In one embodiment, the opening may be a circular opening. The system may prevent the flow of fluid out of the filter housing when an incorrect filter is installed in the filter housing or when no filter cartridge is installed in the filter housing. Additionally, the geometric projection may ensure that the desired seal interface between the filter cartridge and the flow restriction valve is achieved. The flow restriction valve, according to an exemplary embodiment, exhibits improved reliability and a reduced pressure drop during filtration.

According to an exemplary embodiment, a geometric projection of the filter cartridge may engage with an opening in a flow restriction valve of the filter housing. The flow restriction valve may include a valve ball disposed within a chamber. The ball and valve may be configured such that the ball is movable in to a blocking position when fluid pressure is applied to the valve ball. The filter cartridge may include a geometric projection that acts as a blocking means that prevents the valve ball from moving to the blocking position when a fluid pressure is applied.

As illustrated in FIG. 1, a filter cartridge 200 may be placed in a filter housing 230 that includes a filter housing cover 220. A geometric projection 240 of the filter cartridge end plate 210 may engage an opening of a flow restriction valve attached to the filter housing cover 220. The geometric projection may have any appropriate shape. In one embodiment, the geometric projection 240 is in the form of a pin that extends along the longitudinal axis of the filter cartridge. The geometric projection 240 may extend from the center of the end plate 210.

According to an exemplary embodiment, the filter cartridge 200 may be any suitable filter design. In one embodiment, the filter cartridge may be a single filter design. In another embodiment, the filter cartridge may be a double flow filter design. The filter cartridge may be cylindrical. The filter cartridge may include an end plate 210 and filter media. In one embodiment, the end plate 210 may be configured to accommodate a flow restriction valve.

According to an exemplary embodiment, the flow restriction valve includes a valve body 100, a valve support 110, and a valve ball 130 that is configured to restrict fluid flow through the valve when no filter cartridge 200 or an incorrect filter cartridge is installed in the filter housing 230. The geometric projection 240 engages the opening of the valve such that the ball is prevented from blocking the flow of fluid when a designated filter cartridge is installed in the filter housing. FIG. 1 depicts the geometric projection 240 of a designated filter cartridge overlaid on the position of the ball 130 when restricting fluid flow through the valve, showing that the geometric projection 240 physically prevents the ball 130 from restricting fluid flow out of the filter system when a designated filter cartridge is present.

According to an exemplary embodiment, the area between the filter cartridge 200 and the filter housing 230 defines an unfiltered fluid side of the filter system. The interior of the filter cartridge 200 may define a filtered fluid side of the filter system.

As illustrated in FIGS. 2-21, the flow restriction valve includes a valve body 100, valve support 110, valve ball 130, and valve gasket 120, according to an exemplary embodiment. The valve body includes an opening 160 keyed to the geometric projection of the designated filter cartridge. The valve support 110 may be provided with a sealing element 170 to provide a fluid seal between the valve support and the filter housing cover to which it is attached. The sealing element 170 may comprise an o-ring. The sealing element, in conjunction with the flow restriction valve, may be configured to separate the unfiltered fluid from the filtered fluid within the filter housing and filter housing cover.

The valve support may include projections 150 configured to engage the filter housing cover. The projections 150 may be provided with an enlarged end such that the projections engage the filter housing cover and attach the valve support 110 to the filter housing cover. The projections 150 may have any appropriate geometry. The projections 150 may be fingers or tabs. The projections 150 may include an enlarged end such that the projections snap fit over a corresponding feature of the filter housing cover. The snap fit connection allows the adaptation of the flow restriction valve to a variety of filter systems and the retrofit of existing filter cover housings.

The valve body 100 includes fluid flow openings 140 and opening 160 keyed to engage geometric projection of the filter cartridge. The valve body 100 may include one or more enlarged projections 180. The enlarged projections 180 may be configured such that the enlarged projections 180 engage the valve support and attach the valve body 100 to the valve support. The enlarged projections 180 may be separated from the remaining valve body wall by voids or cut-outs to form a tab with an enlarged end. Any number of enlarged projections 180 may be provided on the valve body. As shown in FIGS. 3 and 6, three enlarged projections 180 may be provided on the valve body. The enlarged projections 180 may be configured to snap fit over a corresponding feature of the valve support.

The passage 135 may be configured such that the valve ball 130 completely blocks fluid flow through the passage 135 when pressed against the valve gasket 120. The passage 135 may have any appropriate geometry. The passage 135 may have a circular geometry. Alternatively, the passage 135 may have a geometry that is different than a cross section of the valve ball 130, preventing the valve ball from completely blocking the passage 135.

FIGS. 14-16 depict the valve gasket according to an exemplary embodiment. The valve gasket 120 may include a passage 135 that allows the flow of fluid. The passage may have any suitable geometry. The passage 135 may be a cylindrical passage extending along the central axis of the valve gasket 120. The valve gasket may include a flange 320 and a ridge 310. The flange 320 may be configured to prevent the valve gasket from passing completely through opening 125 in the valve support. The ridge 310 may be configured to secure the valve gasket 120 to the valve support 110. In one embodiment, the ridge 310 is configured to allow the ridge to be pressed through opening 125 in the valve support 110 and to engage the valve support in a snap fit connection. The valve gasket 120 may be formed from any suitable material. For example, the valve gasket may be formed from an elastic material.

According to an exemplary embodiment, the valve body 100 may include one or more fluid flow openings 140. The valve body 100 may include any appropriate number of fluid flow openings 140. In one embodiment, the valve body includes two fluid flow openings 140. The fluid flow openings may be separated by one or more ribs 190. In one embodiment, two fluid flow openings 140 are separated by a rib 190. The rib 190 may be configured to prevent the valve ball 130 from passing through or extending too far in to the fluid flow openings. In another embodiment, The rib 190 may be configured to prevent the valve ball from blocking the entirety of the fluid flow openings 140.

As shown in FIG. 9, for example, the valve body 100 may include a plurality of walls 193. The walls 193 may define the area of the valve body 100 in which the valve ball 130 may travel. The walls 193 may have any suitable geometry. In one embodiment, the walls 193 are parallel and extend inward from the peripheral wall of the valve body to approximately opening 160. The end of each wall 193 that is not adjacent to the peripheral wall of valve body 100 may extend at an angle oblique to the vertical axis of the valve body. In one embodiment, the angle formed by the end of the walls 193 and the vertical axis of the valve body 100 is twenty degrees.

As shown in FIG. 1, for example, the opening 140 in the valve body may have a geometry keyed to the geometrical projection 240 of the filter cartridge. The opening 140 may have a geometry configured to mate to the geometric projection 240. The opening 140 may have a conical surface. The perimeter of opening 140 may bear against the geometrical projection in a manner that creates a seal between the valve body 100 and the geometric projection 240.

As shown in FIG. 19, for example, the valve support 110 may include an opening 125 and partitions 195. The partitions 195 may have any appropriate geometry. The partitions 195 extend inward from a peripheral wall of the valve support 110. The partitions 195 may be configured to delineate the area in which the valve ball may travel. The bottom surface of the valve support 110 may include a curved surface between partitions 195 above opening 125. The opening 125 may be formed in a surface of the valve support 110 that extends at an angle oblique to the longitudinal axis of the valve support. As shown in FIG. 18, for example, the surface in which opening 125 is formed may extend at an angle of twenty degrees from the longitudinal axis of the valve support 110. The valve support 110 may include a void area 115 between the peripheral wall of the valve support and the surface of the valve support in which opening 125 is formed.

As shown in FIGS. 2, 18 and 20, the valve support 110 may include projections 175 configured to retain a sealing element 170. The projections 175 may have any appropriate geometry. For example, the projections 175 may be in the form of ribs. The ribs may extend for a distance less than the thickness of the sealing element 170 to ensure that the sealing element bears and seals against the filter housing cover 220.

As illustrated in FIGS. 2 and 20, the valve support 110 may include a projection 185 configured to accept enlarged projections 180 of valve body 100. The projection 185 may have any suitable geometry. The projection 185 may be configured to engage enlarged projections 180 of the valve body 100 in a snap fit connection.

FIGS. 22-25 illustrate an alternative embodiment. As shown in these figures, the filter system may include a filter cartridge 200 placed in a filter housing 230 that includes a filter housing cover 220.
